Benefits of technology

[0010]In some embodiments, disclosed herein is a system for treating venous insufficiency, the system comprising a catheter assembly comprising a proximal hub having a spin lock, an elongate body operably connected to the proximal hub, and a distal end, the catheter assembly having an elongate body configured to be placed within a perforator vein; an extension tubing having a

Problems solved by technology

When veins weaken and become enlarged, their valves cannot close properly, which leads to venous reflux and impaired drainage of venous blood from the legs.
This could compound the general symptoms of venous reflux, creating additional venous hypertension throughout the region where the perforator is located.
These sites are often associated with skin degradation leading to venous stasis ulcers.
Radiofrequency and laser ablation often require tumescent anesthesia which produces both bruising and pain along the treatment zone for several days post-procedure.
Both can have side effects such as burns and nerve damage, each of which can result in paresthesia or hypoesthesia.
Radiofrequency and laser ablation also can require expensive radiofrequency devices

Embodiment Construction

[0024]Disclosed herein are systems, methods and devices for the minimally invasive treatment of varicose veins and other medical conditions. When used herein with respect to the device, proximal can refer to toward the access insertion site into a blood vessel, while distal refers to away from the access insertion site and in the direction of the patient. In the treatment as applied to the great saphenous vein, proximal may mean cephalad, or towards the head, while distal refers to the caudal direction. In some embodiments an occlusive device is deployed to block the saphenous vein just distal to the Superficial Femoral Vein Junction (SFJ) to coapt the vein walls together encouraging adherence of the walls. This technique may be used with a drug such as sclerosing solution or a device like medical adhesive. In some embodiments, complete vein closure is the desired clinical result of all treatments to mitigate the effects of venous hypertension caused by retrograde venous flow. The o...

Abstract

Systems and methods for the treatment of perforator veins for venous insufficiency are described. The systems can include a catheter assembly comprising a proximal hub, a spin lock on the proximal hub, a elongate body overmolded to the proximal hub, and a distal end, the catheter, the elongate body configured to be placed within a perforator vein; an extension tubing having a proximal female hub, a distal male hub, and an elongate body therebetween, the distal male hub having a spin lock thereon, the distal male hub configured to be attached to the proximal hub of the catheter assembly; a syringe filled with a volume of media including cyanoacrylate; and an injector configured to automatically dispense a bolus of the media sufficient to coapt the perforator vein from the syringe upon actuation of a control on the injector. Methods are also disclosed.

Description

[0001]This application claims the benefit of U.S. Provisional Application No. 61 / 925,478, which was filed on Jan. 9, 2014 and is entitled, “SYSTEMS AND METHODS FOR TREATMENT OF PERFORATOR VEINS FOR VENOUS INSUFFICIENCY,” the entire content of which is incorporated herein by reference.BACKGROUND OF THE INVENTION[0002]Healthy leg veins contain valves that allow blood to move in one direction from the lower limbs toward the heart. These valves open when blood is flowing toward the heart, and close to prevent venous reflux, or the backward flow of blood. When veins weaken and become enlarged, their valves cannot close properly, which leads to venous reflux and impaired drainage of venous blood from the legs. Venous reflux is most common in the superficial veins. The largest superficial vein is the great saphenous vein (GSV), which runs from the top of the foot to the groin, where it terminates at the saphenofemoral junction. There are veins which lead from the superficial veins (great a...
